Being at home, the Packers helmet radio isn't being shut off. McCarthy is transmitting until the snap. I've got a transcript of the snap count:
"First thou settest the Holy Pawns. Then thou must count to three. Three shall be the number of the counting and the number of the counting shall be three. Four shalt thou not count, neither shalt thou count two, excepting that thou then proceedeth to three. Five is right out. Once the number three, being the number of the counting, be reached, then lobbest thou the Holy Hand Grenade in the direction of thine foe, who, being naughty in my sight, shall snuff it."
